Design Manager Licensing

The following licenses are required during the various steps of a design study in Design Manager:

Licensing Schemes

Design Manager supports two different licensing schemes—Default and Unlicensed Design Manager Server. In the Create a File or Load a File dialog, you control the licensing scheme using:

• Direct text entry in the Command text-box. For more information, see Command Line Options Reference.
• The simulation license option.

Licensing Scheme	Command Line Option	Simulation License Option
Default	None
Unlicensed Design Manager Server	-dmnoshare

Default

By default, when you run a design study, Design Manager—that is, the Design Manager server—acquires one session license and shares it with the Simcenter STAR-CCM+ design simulations. This session license can be a serial Simcenter STAR-CCM+ license (ccmpsuite), a Simcenter STAR-CCM+ Power Session license (ccmppower), or a Simcenter STAR-CCM+ Power on Demand license. The Design Manager server keeps the session license until the last design simulation completes.

The Simcenter STAR-CCM+ design simulations obtain their own licenses:

• 1 core license for each concurrent design simulation
• Parallel licenses for the processors on which to run each design simulation

By default, these licenses are Simcenter STAR-CCM+ Power Tokens (DOEtoken feature licenses), but you can also use other licenses following the rules in the License Options Table.

When you run Design Manager in Pre-allocation mode, the Design Manager server automatically pulls all required licenses in advance and shares them with the Simcenter STAR-CCM+ design simulations. These licenses must be available from one license pool only—Design Manager cannot combine multiple licenses from multiple license pools for license sharing.

Unlicensed Design Manager Server

In this licensing scheme, Design Manager does not pull any licenses. The Simcenter STAR-CCM+ design simulations start up as standard Simcenter STAR-CCM+ simulations following the standard stand-alone Simcenter STAR-CCM+ licensing rules. See STAR-CCM+ Licensing.

This scheme allows you to perform design studies using only a single ccmppower license without requiring an additional session license. Use this licensing scheme when you have only ccmppower licenses or Simcenter STAR-CCM+ Power on Demand licenses available.

Example 1: Suppose you have the following licenses available:

• 3 ccmpsuite
• 50 DOEtoken

You want to run 3 design simulations concurrently, each on 16 processors. Design Manager pulls the following licenses:

Licensing Scheme	License Usage
Default
Unlicensed Design Manager Server

In this case, the default licensing scheme is more appropriate: The Unlicensed Design Manager Server scheme saves 3 DOEtoken but requires two more ccmpsuite, which are more valuable than DOEtoken.

Example 2: Suppose you have the following licenses available:

• 3 ccmpsuite
• 3 ccmppower

Again, for 3 concurrent design simulations, each on 16 processors, the following licenses are pulled:

Licensing Scheme	License Usage
Default
Unlicensed Design Manager Server

In this case, the Unlicensed Design Manager Server scheme is more appropriate, as it requires no ccmpsuite.

Common Licensing Scenarios
